The present invention relates to a mobile communication system having a coordinated communication mode in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner and an uncoordinated communication mode in which radio communication is performed between a user equipment and a base station without coordinating with another base station, in which radio communication is performed by selectively using any of the coordinated communication mode and the uncoordinated communication mode. The coordinated communication in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner and the uncoordinated communication in which radio communication is performed between a user equipment and a base station without coordinating with another base station are selectively used in an appropriate manner, with the result that a mobile communication system capable of exerting its performance in accordance with a situation can be provided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A mobile communication system, which has a coordinated communication mode in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner and an uncoordinated communication mode in which radio communication is performed between a user equipment and a base station without coordinating with another base station, wherein radio communication is performed by selectively using any of said coordinated communication mode and said uncoordinated communication mode in accordance with a capability of said user equipment.
2. A base station, which has a coordinated communication mode in which radio communication is performed between a user equipment and said base station with coordinating with another base station and an uncoordinated communication mode in which radio communication is performed between a user equipment and said base station without coordinating with another base station, wherein radio communication is performed by selectively using any of said coordinated communication mode and said uncoordinated communication mode in accordance with a capability of said user equipment.
3. A user equipment, which is capable of performing radio communication with a plurality of base stations, said plurality of base stations having a coordinated communication mode in which radio communication is performed with coordinating with another base station and an uncoordinated communication mode in which radio communication is performed without coordinating with another base station, wherein radio communication is performed by selectively using any of said coordinated communication mode and said uncoordinated communication mode in accordance with a capability of said user equipment.
